This invention relates to a rece tacle which includes a hollow sheet metal ody and a bottom closing one end of the body and chimes at opposite ends of the body, t e receptacle bemg for example, an ash barrel, or other container not necessarily closed at both ends.

a The object of the invention is to provide a strong and durable receptacle, having a minimum number of parts, which are permanently mterengaged or interlocked with out rivets, and are of such form that they ma be rapidly and'inexpensively assembled an interlocked. I

The same reference characters indicate the same parts in all of the figures.

A composite receptacle constructed in accordance with my invention is provided as hereinafter described with laminated chimes and comprises two sheet metal end hoops 13 and a hollow sheet metal body which may be composed of a single piece of sheet metal 60 united at opposite edges to form a one piece cylindrical body 12, the hoops being within the end portions of the body. The metal of which the hoops are made is considerably thicker and stiffer than that of which the 05 body is made, the thickness of the hoop metal being preferably about one-twentieth of an inch, and the thickness of the body metal about one-eightieth of an inch, although these relative thicknesses may be varied.

The hoops have preformed outwardly curled portions 14 constituting approximately tubular formers overhanging the outer surfaces of the hoops and integral therewith, each former being a hollow rolled bead having a free edge which is spaced from the outer surface of the hoop to form an annular mouth adapted to receive an end portion of the body 12. The curled portions 14 also constitute external chime layers.

The hoops 13 are substantially completed before they are assembled with the body, the inner surface of the formers 14 being curved outward from the outer surface of the hoop and presenting deflecting or forming m- 86 ternal surfaces adapted to roll the end portions of the body and form thereon hollow rolled beads 16 constituting internal chimev layers nested in the formers by the operation of forcing the hoops toward each other 90 from the positions shown by Figure 9 to those shown by Figure 10. The rolled beads 16 are therefore interlocked with the formers.

'so that the hoops are securely engaged with the body wholly by portions of the material of the hoops and body,-no rivets or other additional fastenings being required. The

dyas originally ormed has plain or undefiected end portions which are converted into the beads or enlargements 16.

17 designates a bottom having a continuous downwardly projecting flange 18 and made of relatively thin and flexible sheet material like that of the body 12. The flange 18 is originally formed as shown by Figure 5, and is changed to the form shown by Figure 2 by the operation of forcing the hoops toward each other, this'operation causing the former 14 of the lower hoop to form :1 rolled bead 19 on the lower portion of the bottom flange, said bead being nested, with the bead 16 on the lower end of the body 12. in the former of the lower hoop, so that the bead 19 forms an additional internal layer of the lower chime.

In assembling the described parts the bottom flange 18 is interposed between the lower hoop and the lower end portion of the body as shown by Figure 9, the bottom 17 being spaced above the lower hoop.

The 0 eration of forcing the hoops toward each 0t er forces the bottom against the upper edge of the lower hoop, as shown by Fi ure 2.

11 case the body does not require external reinforcement, the entire receptacle may include only the body, a one piece body such as the body 12, the hoops and the bottom, said parts being united as above described.

refer, however, to include in the construction of the body suitable reinforcing means to enable it the better to withstand rough usage.

Two forms of reinforcing means are shown by the drawings. :The form shown by Figures 1, 2, and 6 includes a plurality of strips 21 of sheet material characterized like that of the body 12, superposed and spaced apart on the one piece body and provided with longitudinally extending corrugations forming stiffening ribs 22. The strips 21 are originally formed with plain end portions projecting'from opposite ends of the ribs, one of said end portions being shown by Figure 6. The strips 21 are first assembled with the one piece body 12 and the body and hoops as shown by Figures 1 and 2, and the plain end portions of the strips are changed to the form shown by Figure 2 by the operation of forcing the hoops toward each other, this operation causing the formers of the two hoops to form rolled beads 23 on the end portlons of the strips 21, said beads beingnested with the body beads 16 and the bottom flange bead 19, as shown by Figure 2, so that they form additional internal layers of the laminated chimes.

The alternative form of reinforcing means 1 comprises a hollow jacket 120 which may be of sheet material characterized like that of the one piece body 12, and proportioned to cover and bear on the external surface thereof, one end portion of said jacket being shown by Figure 8. The jacket may be corrugated to provide longitudinal stiffening strips 21.

ribs 220. The end portions of the jacket are originally formed as shown by Fi ure 8, said end portions being adapted to c converted into rolled beads nested with the other beads as are the beads 23 on the reinforcing In either case the reinforcing means constitutes a structural part of the body.

When the parts are assembled as shown by Figure 9, the lower hoop may rest on a fixed support 25, and the upper hoop may be depressed by a moving head or presser 26 to decrease the distance between the hoops as shown by Figure 10.

It will be seen that the laminated chimes which include the formers 14 are tubular and substantially cylindrical, and that the layers have free edges spaced from the body 12, as shown by Figures 2,7 and 10.

The chimes are therefore radially compressible so that their diameter ma be reduced by simultaneously forcing t e free edges inward toward the body to compact the chimes and increase resistance to force tending to withdraw the inner layers from the outer layers provided by the formers 14. The' chimes may be thus compressed by crimping dies 27, (Figure 11) having acting faces 28 adapted to force the free edges of the chime layers inwardly as indicated by Figure 12.

I will now briefly state the distinguishing features of the receptacle.

The end hoops 13 have portions 14 curled therefrom and constituting approximately tubular external chime layers having free edges spaced from the body 12, said body being either reinforced or without reinforcement. The portions 14 have internal forming surfaces extending interruptedly from thejunction of the curled portions with tho hoops to said free edges. Said edges are free in the sense that they face the body and are movable inward toward it.

The body 12, with or without the described reinforcing means, has relatively flexible end portions curled therefrom by the internal forming surfaces of the portions 1 1, and coir stituting approximately tubular internal chime layers having free edges facing and spaced from the body, and outer surfaces extending uninterruptedly from the junction of said curled portions with the body to the free edges, and conformed closely to-all portions of the forming surfaces of the curled portions 1 1. r

The curled hoop and body portions form laminated chimes in which all of said free edges are spaced from, and movable simultaneously toward the body, so that the diameter of the chimes may be reduced, as may be seen by comparing Figure 10 with Figure 12, b forcing said free edges toward the body to increase resistance to force tendin reduced by forcing said edges toward the b0 y,- so that resistanceto force tending to withdraw the curled body ends from the curled hoop portions is increased.

In testimony whereof I have afiixed my signature.

nally contracted to the final form shown by Figure 11.

It will also be seen that if the hoop portions 14 were allowed to remain permanently in the relatively open condition shown by Figures 9 and 10, the curled body ends could be somewhat easily withdrawn from the curled hoop ends, and that when the hoop portions are contracted, as shown by Figure 12, the resistance to force tending to withdraw the body ends from the hoop ends is greatly increased.
